Abstract

a. Flèche flexible. b. Elle comprend : une flèche allongée conçue pour fléchir sous des charges prédéterminées et dans laquelle est défini un plan neutre ou les contraintes sont nulles, un support ayant une première et une seconde extrémités, une ouverture percée dans la première extrémité, un joint d'articulation formé à la seconde extrémité et un joint soudé s'étendant pratiquement tout autour de l'ouverture et qui est contigu audit plan neutre afin de fixer le support à la flèche avec la seconde extrémité au support s'étendant au-delà de cette dernière. c. Concerne les flèches des véhicules de travaux publics et autres.at. Flexible arrow. b. It comprises: an elongated boom designed to flex under predetermined loads and in which a neutral plane is defined where the stresses are zero, a support having first and second ends, an opening drilled in the first end, a hinge joint formed at the second end and a welded joint extending substantially all around the opening and which abuts said neutral plane to secure the support to the boom with the second end to the support extending beyond the latter. vs. Concerns the arrows of public works vehicles and others.
